HESI A2 Vocabulary 2023

Correct Answer: A

Rationale: The correct answer is A: Ripple. In this sentence, 'undulate' is used to describe a smooth, wave-like motion of the muscles, which aligns with the meaning of 'ripple.' The word 'undulate' implies a continuous and flowing movement, resembling the gentle and rhythmic movement of waves. The other choices, shake, flatten, and unknot, do not capture the specific fluid and continuous motion described in the sentence. 'Shake' implies a more abrupt and irregular movement, 'flatten' suggests a completely different action of making something flat, and 'unknot' refers to the action of undoing a knot, none of which fit the context of the sentence.

Correct Answer: A

Rationale: The correct answer is A: Permeable. Permeable describes a screen or filter because it allows substances to pass through. Screens and filters are designed to allow certain particles or substances to flow through while blocking others. Choice B, Incendiary, is incorrect as it means causing fires. Choice C, Exuding, is incorrect as it means to discharge or emit. Choice D, Resilient, is incorrect as it means able to withstand or recover from difficult conditions. The key in this question is understanding the function of a screen or filter, which is to permit the passage of some substances while blocking others, making the term "permeable" the most appropriate choice.

Correct Answer: B

Rationale: The correct answer is B: Separated. In this context, 'winnowed' means to separate the applicants from the group based on their qualifications or suitability. The process involves carefully selecting or eliminating individuals. The other choices are incorrect because: A: Escorted - This implies guiding or accompanying someone, which is not the action described in the sentence. C: Elevated - This suggests raising someone to a higher position, which does not fit the context of eliminating applicants. D: Summoned - This means calling someone to a place, which is not what is happening in the sentence where applicants are being removed from the group.

Correct Answer: C

Rationale: The correct answer is C: Managed and run. In the context of the sentence, "operated" refers to the management and running of the hospitals by administrative medical groups. This choice best fits the context of the sentence as it accurately describes the action being taken by these groups. Explanation: - A (Performing surgery): This choice is incorrect as the word "operated" in the sentence does not refer to performing surgery but rather to the overall management and running of the hospitals. - B (In effect): This choice is incorrect as it does not fully capture the meaning of "operated" in the context of the sentence, which implies active management and operation of the hospitals. - D (Brought about): This choice is incorrect as it does not accurately describe the ongoing management and running of the hospitals by the administrative medical groups.

Correct Answer: A

Rationale: The correct answer is A: Bitter. Acrid refers to a sharp and unpleasant taste or smell, often associated with bitterness. Bitter is the most synonymous term, as it conveys the same sharp and unpleasant quality. Smoky, nimble, and severe do not align with the definition of acrid, making them incorrect choices. Smoky refers to a smell associated with smoke, nimble relates to agility, and severe conveys seriousness or harshness, none of which capture the essence of acrid. Therefore, option A is the most appropriate synonym for acrid in this context.
